Generally speaking, having a veneer put in place is practically painless. However, some people may feel some mild discomfort during the application or for a short time after. But any sensitivity you might feel should go away on its own in a few days.
Veneers can be a quick, safe and effective treatment for nearly everyone. However, like any treatment, there can be some exceptions. For example, if we find any untreated tooth decay, acid erosion, gum disease or you grind your teeth, veneers may not be right for you. If this is the case, your dentist will take the time to discuss any restorative options.
A properly and professionally placed veneer that is well cared for though good oral hygiene and diet can easily last a lifetime.
However, if you neglect your oral health and consume lots of fizzy drinks, sweets or other sugary treats, your tooth/teeth will still a target of tooth decay and your veneer may need to be replaced.
